Abstract

Obviously, the dependence of intensity of Lyoluminescence on the temperature is extremely interesting from the experimental and theoretical point of view. The investigation of the temperature dependence of Lyoluminescence provides important information’s as to the nature of luminescence centers. Extensive studies have been made on the temperature dependence of the LL of several organic and inorganic crystals. This paper reports the effect of temperature on the Lyoluminescence of stroncium doped sodium chloride sample. When the doped NaCl samples irradiated using 60Co source are dissolved in a suitable solvent like distilled water, the LL intensity increase with time, attains a maximum value, then it decreases and finally disappears. Peak intensity is maximum at a specific temperature.
